Non-Functional Requirements Elicitation Guideline for Agile Methods

One of the essential activities in software development is elicitation of requirement. Majority of the studies has pointed out that less attention is given to the NonFunctional Requirement (NFR). The negligence of NFR elicitation is due to lack of knowledge of the user and developer about NFR. Our study presents elicitation guidelines for NFRs in agile methods. This guideline will helps developers as well as users in agile methods. A case study is conducted on the group of master students for eliciting NFR with the help of elicitation guidelines. In addition, the initial results were obtained by extracting NFRs from eProcurement document that carries requirements of major European Union projects. The result of the case study is positive and encouraging for the new developers and users having less awareness about NFRs. Furthermore, the study describes the role of cloud computing in agile methods, especially in elicitation activity

Bioassay evaluation of toxicity reduction in common effluent treatment plant

This paper investigates the utility and validity of bioassay toxicity testing using Daphnia magna straus as test organism for monitoring the common effluent treatment plant (CETP) receiving both industrial as well as domestic effluent. The average daphnia toxicity (Gd) at inlet, after primary settling tank (PST), secondary settling tank (SST) and tertiary treatment unit were reported as Gd-16, Gd-12, Gd-4 and Gd-1 respectively. However, a cumulative percentage removal in toxicity after PST, SST and tertiary treatment units was observed as 25%, 75% and 100%, respectively, during entire study period. It showed that a complete removal in daphnia toxicity (Gd) i.e.100% had been achieved only after tertiary treatment unit involving Dual Media Filters followed by activated carbon filters. Further attempts have been made to establish the relationship between key wastewater constituents i.e. Chemical Oxygen Demand (COD) and Suspended Solids (SS) with respects to daphnia toxicity (Gd). It was observed that COD and SS show a statistically significant correlation (r2) with daphnia toxicity (Gd) i.e. 0.89 and 0.81, respectively. Thus COD and SS can serve as a regulatory tool in lieu of an explicit toxicity standard (to check and improve the operational status of wastewatertreatment plants in time)

The effect of endurance training on the level of tissue IL-6 and VEGF in mice with breast cancer

زمینه و هدف: تمرینات ورزش پتانسیلی در جهت پیشگیری از سرطان پستان دارد. هدف پژوهش حاضر بررسی اثرات پیشگیری و کمک درمانی تمرینات ورزشی بر سایتوکاین های درگیر در رگ زایی تومور سرطان پستان وابسته به گیرنده استروژن می باشد. روش بررسی: در این مطالعه مداخله ای 50 سر موش بالب سی ماده به طور تصادفی در چهار گروه قرار گرفتند. پس از آشناسازی با محیط دو گروه از موش ها به مدت 8 هفته تمرین استقامتی تداومی را انجام دادند و سپس سلول های سرطانی وابسته به استروژن (MC4-L2) به همه موش ها تزریق گردید. پس از آن یک گروه از موش های تمرین کرده و یک گروه از موش های تمرین نکرده به مدت 6 هفته، 5 روز در هفته تمرینات استقامتی را انجام دادند. حجم تومور به صورت هفتگی با کولیس دیجیتالی اندازه گیری شد. در پایان موش ها قربانی شدند و بافت تومور برداشته و سطوح سایتوکاین های اینترلوکین 6 (IL-6) و فاکتور رشد اپی تلیال عروق (VEGF) با روش الایزا اندازه گیری شد. یافته ها: بین گروه ها در میزان مقادیر IL-6 و VEGF و میزان رشد تومور تفاوت معناداری وجود داشت (001/0PP). نتیجه گیری: با توجه به افت مقادیر IL-6 و VEGF در گروه هایی که قبل از سرطانی شدن و پس از سرطانی شدن تمرینات ورزشی را انجام دادند؛ می توان گفت که تمرینات ورزشی علاوه بر نقش پیشگیرانه بسیار موثر، دارای نقش درمانی در تومورهای وابسته به گیرنده استروژن نیز می باشند

Efficient Excitation of Micro/Nano Resonators and Their Higher Order Modes

We demonstrate a simple and flexible technique to efficiently activate micro/nano-electromechanical systems (MEMS/NEMS) resonators at their fundamental and higher order vibration modes. The method is based on the utilization of the amplified voltage across an inductor, L, of an LC tank resonant circuit to actuate the MEMS/NEMS resonator. By matching the electrical and mechanical resonances, significant amplitude amplification is reported across the resonators terminals. We show experimentally amplitude amplification up to twelve times, which is demonstrated to efficiently excite several vibration modes of a microplate MEMS resonator and the fundamental mode of a NEMS resonator

Plants and Small Molecules: An Up-and-Coming Synergy

The emergence of Arabidopsis thaliana as a model system has led to a rapid and wide improvement in molecular genetics techniques for studying gene function and regulation. However, there are still several drawbacks that cannot be easily solved with molecular genetic approaches, such as the study of unfriendly species, which are of increasing agronomic interest but are not easily transformed, thus are not prone to many molecular techniques. Chemical genetics represents a methodology able to fill this gap. Chemical genetics lies between chemistry and biology and relies on small molecules to phenocopy genetic mutations addressing specific targets. Advances in recent decades have greatly improved both target specificity and activity, expanding the application of this approach to any biological process. As for classical genetics, chemical genetics also proceeds with a forward or reverse approach depending on the nature of the study. In this review, we addressed this topic in the study of plant photomorphogenesis, stress responses and epigenetic processes. We have dealt with some cases of repurposing compounds whose activity has been previously proven in human cells and, conversely, studies where plants have been a tool for the characterization of small molecules. In addition, we delved into the chemical synthesis and improvement of some of the compounds described

Educational needs of patients, families, and healthcare professionals to support the patient journey in haemophilia gene therapy in the UK

With the first gene therapies for haemophilia approved by the European Commission, the US Food and Drug Administration, and the Medicines and Healthcare products Regulatory Agency, it is important to consider the remaining unmet needs and challenges that may arise throughout patients’ treatment journeys. We discuss existing unmet needs and important considerations prior to, during, and following haemophilia gene therapy treatment in the UK, and propose potential next steps. Key areas for attention are education, psychological support, and guidance on implementation. Strategies are urgently required to fulfil these needs. An immediate priority for information providers should be comprehensive education for people with haemophilia (PWH) and healthcare professionals (HCPs). Greater access to resources and training in psychological services will be required throughout the treatment pathway. More specific guidance is required to define the implementation model, criteria for accreditation, and responsibilities of care centres. Furthermore, PWH may revisit discussions with HCPs multiple times pre-infusion, thus the patient journey is unlikely to be linear. Consideration of these challenges, and of potential strategies to address them, will be integral to optimising the future success of this promising therapy

Evaluation of efficacy and safety of a polyherbal Unani formulation in diabetes mellitus type 2 (Zayābīṭus Sukkari Qism Sāni) - a randomised controlled clinical study

15-20Diabetes mellitus type 2 (Zayābīṭus Sukkari Qism Sāni) is a major health concern in 21st century. Despite tremendous advances in modern sciences, there is a lack of relatively safe and effective drug for its management. The primary objective of this study was to evaluate the efficacy and safety of a polyherbal Unani formulation containing Gurmar booti (Gymnema sylvestre), Gilo (Tinospora cordifolia) and Jamun (Syzygium cumini) in the management of Diabetes Mellitus Type 2 (DMT2). It was a randomised controlled clinical study conducted on 60 participants of DMT2 inadequately controlled by diet and exercise. The test drug was given to group-A participants (n=30) 6 g twice daily orally for 12 weeks and the standard drug metformin (500 mg) was given twice daily orally to group-B participants (n=30). It was observed that the difference between the Mean (± SD) value of fasting blood glucose (FBG), postprandial blood glucose (PPBG) and glycosylated haemoglobin (HbA1c) in Test and Control groups at the end of the study in comparison to baseline was significant (p<0.05). This study concludes that the test drug was effective in reducing FBG and PPBG significantly in diabetic participants’ at 12 weeks of treatment
